Scope of the collection:
These are a subset of the records of the Harvard College Observatory. These photographs depict the staff activities including travel and research, of the Harvard College Observatory as well as the the landscape, buildings, and equipment in Cambridge and at observatory stations in Colorado, California, Jamaica, and South America (chiefly Peru). Research was primarily astronomical, but also included some meteorological observation.

E Plates:
This subseries contains chiefly images of facilities, equipment, personnel, and environs of the Harvard College Observatory in Cambridge, Massachusetts. The purpose of this series was perhaps to demonstrate the activities of the Observatory and the equipment they used to gather data. This series may have been assembled for display at the Pan American Exposition in 1904 in St. Louis.
